Daryl G. Kimball is Executive Director of the Arms Control Association. Following is the text of his statement on the choice of John Bolton,former U.S. Permanent Representative to the UN in New York, as President Donald Trump's National Security Advisor.

WASHINGTON, D.C. (IDN) – The United States already faces an array of complex and dangerous foreign policy challenges that require pragmatic decision and sober diplomatic engagement with American allies and foes alike.

With the choice of John Bolton as his National Security Advisor, President Donald Trump has chosen someone with a record of a hostile attitude toward multilateral security and arms control agreements and effective international institutions designed to advance U.S. national security and international peace and security.

Bolton's extreme views could tilt the malleable Mr. Trump in the wrong direction on critical decisions affecting the future of the Iran nuclear deal, the North Korean nuclear crisis, and the strained U.S. relationship with Russia, among other issues.

Bolton is a nonproliferation hawk, but he has a disturbing and bellicose record of choosing confrontation rather than dialogue, politicizing intelligence to fit his worldview, and aggressively undermining treaties and negotiations designed to reduce weapons-related security threats.

In the early 2000s, Bolton was among those in the George W. Bush administration who opposed further dialogue with North Koreawhich allowed North Korea to advance its nuclear program and test nuclear weapons. More recently, has argued that the United States should launch a “preventive attack” on North Korea, which would result in a catastrophic war. His approach runs counter to Mr. Trump’s own stated policy of using sanctions pressure and diplomatic engagement, including a summit with Kim Jong-un, to halt and reverse North Korea's nuclear and missile programs.

Bolton has repeatedly criticized the 2010 New Strategic Arms Reduction Treaty (New START) with Russia, which is one of the few bright spots in the troubled U.S.-Russia relationship and continues to enjoy strong support from the U.S. military. Last year Bolton called the treaty “an execrable deal.”

While undersecretary of state for arms control and international security during the George W. Bush administration, Bolton cherry-picked the findings of intelligence community assessments of that country’s weapons of mass destruction capabilities, and was a key player in making the Bush administration’s flawed case for the war in Iraq—a war that Donald Trump has correctly ridiculed as a catastrophic American foreign policy blunder.

If Bolton succeeds imposes his worldview on Donald Trump’s improvisational and impulsive foreign policy approach, we could be entering in a period of crisis and confrontation.

In particular, if Bolton convinces Trump to unilaterally violate the 2015 Joint Comprehensive Plan of Action in May when the U.S. is due to renew sanctions waivers, it would not only open the door to the re-emergence of Iran as a nuclear weapons proliferation risk, but it would undermine President Trump’s very tentative diplomatic opening with North Korean leader Kim Jon-un.

In the next year or so, Trump will need to decide whether or not to engage in talks with Russia about extending the 2010 New Strategic Arms Reduction Treaty, which is due to expire in 2021. Without the treaty, there would be no verifiable limits on the world’s two largest nuclear arsenals for the first time since 1972.

We can ill-afford two nuclear proliferation crises, as well as abandoning a key brake on the growing risks of renewed U.S. and Russian nuclear competition and arms racing.

Congress will need to play a stronger role to guard against further chaos and confusion in U.S. foreign policy, prevent the White House from blundering into unwise and catastrophic military conflicts, and to halt further degradation of the credibility of the United States as a responsible global leader.
